Definitions

  • the invention relates to liquid soap preparations which are suitable as cleaners for hard surfaces, in particular as household and general-purpose cleaning agents.
  • Liquid soaps are aqueous solutions of salts of higher fatty acids. It is known that such liquid soaps can readily be prepared from potassium and alkanolamine salts of higher fatty acids with 12 to 18 carbon atoms, in particular from unsaturated fatty acids. However, alkanolamines are also increasingly rejected for toxicological reasons.
  • Aqueous alkali soaps of the known type tend to form heterogeneous gels even at low concentrations; this instability is exacerbated by the addition of perfume oils.
  • soap preparations tend to form difficult-to-dissolve calcium soaps with the hardness constituents of the water, which are noticeable in the cleaning liquor as fluffy precipitate and on the surfaces to be cleaned as a greasy residue.
  • liquid soap preparation which contains 10 to 30% by weight of fatty acids, of which 0.1 to 10% by weight in unsaponified form, and which lime soaps can contain as opacifiers.
  • Liquid soap compositions were known from ÜS-2,792,347, which remain liquid in high concentration due to a special fatty acid combination. The task was to develop a liquid soap preparation which, at a concentration of up to 10% by weight of fatty acids, is a homogeneous, non-gelling and easily flowable and pumpable liquid and does not separate lime soap during storage or lime soap residues when used in hard water leaves the cleaned surfaces.
  • liquid cleaning compositions for example: B. perfume oils, dyes, complexing agents, antioxidants, preservatives, bleaches, thickeners. Superfatting agents or builder salts.
  • Preferred unsaturated fatty acids are oleic acid or technical mixtures of fatty acids with 12 to 22 carbon atoms, which are obtained by hydrolysis of vegetable or animal oils and fats and which, owing to their content of oleic acid and also linoleic acid, elaidic acid, Palmitoleic acid or erucic acid have an iodine number in the range of 40 to 150.
  • suitable fatty acids are e.g. B. palm oil fatty acid, cotton oil fatty acid, peanut oil fatty acid or mixtures of soy or sun flower oil fatty acid with taig fatty acid.
  • Mixtures of these unsaturated fatty acids with coconut oil fatty acid can also be used as long as the iodine number of these mixtures is within the specified range.
  • Natural fatty acid or fatty acid fractions with an iodine number of 60 to 100 are preferably used as unsaturated fatty acids.
  • the saponification of the fatty acids takes place in the production of the liquid soap by reaction with potassium hydroxide or with a mixture of potassium and sodium hydroxide, the proportion of the potassium hydroxide should be more than 50 mol% of the mixture.
  • the saponification is usually carried out using a stoichiometric amount of the alkali metal hydroxide. However, a slight deficit of the alkali metal hydroxide can also be used, so that up to 10% by weight of the fatty acid remain unsaponified and act as superfatting agents.
  • the saponification can also be carried out with the aid of potassium and optionally sodium carbonate in such a way that an amount of 0.2 to 2% by weight of alkali carbonate remains in the liquid soap after the saponification. Otherwise, the sodium or potassium carbonate is added to the batch separately.
  • Suitable water-soluble, oxyethyl group-containing nonionic surfactants are, for. B. the adducts of ethylene oxide with fatty alcohols with 12 to 22 carbon atoms, fatty acids with 12 to 22 carbon atoms, with fatty acid monoglycides, with fatty acid sorbitan monoesters, with fatty acid methylglucoside monoesters, with fatty acid monoethanolamides Alkyl (Ci2-Ci8) glucoside or on alkyl (C8-Ci5) phenols.
  • the adducts with an HLB value of 10 to 18 are preferably suitable, the HLB value being according to the formula
  • L is the weight fraction of the lipophilic fatty alkyl, fatty acyl or alkylphenyl group in% of the molecular weight of the nonionic surfactant.
  • Suitable water-soluble oxyethyl group-containing anionic surfactants are, for. B. the compounds with the general formula
  • R is a, preferably linear, alkyl group having 12 to 18 carbon atoms
  • x is a number from 1 to 30 and
  • A is an anionic group
  • B. represents a -SO3 ", -P ⁇ 3H ( ⁇ ) or -CH2-CO ⁇ ( ⁇ ) group and M is a monovalent cation which forms a water-soluble salt.
  • anionic surfactants are obtained from addition products of 1 to 30 mol ethylene oxide linear fatty alcohols with 12 to 18 carbon atoms obtained by sulfation, phosphation or carboxymethylation by known processes. Suitable products are commercially available.
  • Preferred suitable anionic surfactants are the alkyl polyglycol ether sulfates.
  • the water solubility of the synthetic, nonionic or anionic surfactant should be at least so high that the maximum amount of 3% by weight is clearly soluble in the liquid soap preparation at 20 ° C. However, preference should be given to a clear water solubility of more than 10% by weight at 20.degree.
  • a preferred embodiment of the invention are those liquid soap preparations which, as a water-soluble synthetic surfactant, contain a sulfuric acid half-ester salt of an alkyl polyglycol ether with 10 to 18 carbon atoms in the alkyl group and 1 to 25 glycol ether groups, preferably as the sodium salt, or an alkyl or alkenyl polyglycol ether with 10 to Contain 18 carbon atoms in the alkyl or alkenyl group and 6 to 30 glycol ether groups.
  • the liquid soap preparations according to the invention can contain customary auxiliaries and additives in a small amount of up to about 5% by weight in total.
  • auxiliaries and additives are such.
  • the liquid soap preparation according to the invention is prepared in the customary manner, for. B. by dissolving water, potassium hydroxide, potassium or sodium carbonate and any complexing agents which may be present in water, heating the solution to about 80 ° C. and gradually stirring to about 50 ° C. warmed fatty acid admits.
  • Saponification occurs with the formation of a transparent, syrupy solution.
  • the synthetic oxyethyl-containing surfactant e.g. B. in the form of an approximately 25% solution of an alkyl ether sulfate in water at 25 ° C.
  • the perfume oil and, if appropriate, a small amount of potassium peroxodisulfate are added.
  • the viscosity was determined using a Brookfied rotary viscometer, type RVT, spindle 3 at 20 rpm.
